Given your requirement for a car for road trips, we recommend looking at the more powerful options within your budget, rather than the more feature-packed ones.
The Maruti Suzuki Ignis is a good fit for your needs. It has a nice 1.2-litre engine, and Maruti's easy-to-access service network also counts for a lot when venturing out of city limits.
Citroen C3 is the best-to-drive car within your budget, but the service network is small.
Tata Tiago and Tata Punch are also options to consider. They feel tough, and this adds greatly to confidence on a road trip.
